I'm playing Minecraft on a server that has tweaked the Hopper speed to be faster. No matter what size is, the stack still goes through. The reason for this speed tweak is a plugin the server has for faster item transport.
I'm trying to find a way to filter items by stack (or sometimes lower), however none of the item filters can handle the hopper speed, and I'm not a Redstone genius. What can I do in this case?
